Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety fence in a warehouse facility that is equipped with a shelf and a device for automatically performing order picking.

2. Description of the Related Art In a warehouse facility, for example, as shown in FIG. 4, shelves 3 having a large number of load storage spaces 2 vertically and horizontally are arranged on both sides of a passage 1 to store loads 4. . Outside the ends of these shelves 3, a load 4 is placed by a forklift 5 or the like.
A loading and unloading area 6 for delivering the items is provided. In addition, a loading / unloading device 8 is arranged in the passage 1 so as to be movable along a fixed path 7. The loading / unloading device 9 provided on the loading / unloading device 8 is vertically movable and can be horizontally retracted, so that the load on the shelf 3 can be reduced. The load 4 is transferred between the storage space 2 and the handling space 6.

By the way, at the end of the fixed path 7, a plan view surrounding one end of the loading / unloading device 8 is U-shaped so that a person or the forklift 5 does not come into contact with the loading / unloading device 8 located at a position facing the loading / unloading area 6. The fence 10 is installed.

Problems to be Solved by the Invention When the shelves 3 are arranged along the wall surface 11,
When a plurality of items are installed in parallel, the forklift 5 and the like load and unload the load 4 into and from the loading and unloading place 6 by moving the forklift 5 and the like in parallel with the constant path 7 as indicated by an arrow A. However, at the end of the fixed path 7, a U-shaped fence 10
Is arranged, and this fence 10 has been one of the causes of hindering the operability of the forklift 5 and the like and reducing the work efficiency.

An object of the present invention is to provide a safety fence in a warehouse facility that can solve the above problems and improve workability such as a forklift.

Means for Solving the Problems In order to solve the above problems, the present invention is a shelf having a plurality of compartment storage spaces in the vertical direction and the horizontal direction, and a cargo handling field arranged outside the end of the shelf, Equipped with a shelf and a loading / unloading device having a loading / unloading device that can move up and down and move laterally in a fixed path along the front of the loading / unloading area, and the loading / unloading device is parallel to the loading / unloading area with the fixed path. In a warehouse facility that moves goods in and out to load and unload cargo, a fence to be placed outside the cargo handling area at the end of the fixed route is formed in a U-shape in plan view surrounding the end of the fixed route. At the same time, the space between the facing surfaces of the fence is narrowed toward the end of the fixed path.

Action With the above configuration, compared to the conventional fence, the width of the connecting surface side of the facing surface is narrowed to prevent both corners from traveling to the moving passage side of the loading / unloading device. Since the loading / unloading device such as a forklift can be guided by inclining the loading / unloading device to the loading / unloading area, the moving passage of the loading / unloading device can be widened and the workability of the loading / unloading device can be improved.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. The same members as those of the conventional example are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 1 and FIG. 2, the shelf 3 has columns 21 standing upright at four corners of the load storage space 2, arms 22 projecting at opposite positions of the columns 21 on the left and right, and front and rear arms. Arm rails 23 that support the bottom of the load 4 across 22 are connected. In addition, the loading / unloading device 8 that can travel freely on the fixed path 7 is a traveling platform 25 guided by a floor rail 24, and an upper frame 29 at the upper end that is erected on the traveling platform 25 has a ceiling rail.
A pair of front and rear posts 27 guided by 26, a lifting platform 28 guided by the posts 27 to move up and down, and a multistage fork-shaped loading / unloading tool 9 provided on the lifting platform 28 and capable of retracting in the lateral direction. It is equipped with a traveling drive unit 30 and a lifting platform 28 on the traveling platform 25 side.
The lifting drive device 31 and the receiving side operation box 32 are provided. The loading / unloading device 9 has a loading / unloading tool 9 at the loading / unloading area 6.
Between the forklift 5 and the forklift 5 (an example of loading / unloading device)
A cargo receiving stand 33 is arranged which can be handed over.

A fence 35 is installed outside the cargo handling area 6 at the end of the floor rail 24 so that the worker or the forklift 5 does not come into contact with the loading / unloading device 8. As shown in FIG. 3, the fence 35 is formed of a connecting plate portion 36 and opposite side fences 37A and 37B facing each other, and is formed in a U-shape in plan view surrounding the end of the floor rail 25. The distance L between the tips of the opposite side fences 37A, 37B is set larger than the width 1 of the connecting plate portion 36 on the end side of the floor rail 24 so that the side fences 37A, 38B are inclined with respect to the floor rail 24. Will be placed. The front ends of the side fences 37A, 38B are arranged close to the passage 1 side of the cargo receiving table 33, and the front plate portion 36 is provided with a door 38 that goes in and out of the passage 1. Further, the front plate portion 36 is provided with a transmission side operation box 39 having an operation panel 39a for remotely controlling the loading / unloading device 8.

According to the above embodiment, the width l of the connecting plate portion 36 is made narrower than that of the conventional fence body so that the forklift 5 moving passage outside the fence body 35 is provided.
Since 40 can be widened and both side fences 37A and 38B can be inclined toward the loading / unloading area 6 side to guide the loading / unloading movement of the forklift 5 along the fixed route 7, the operation range of the forklift 5 can be widened and the work efficiency can be improved. Can be made.

EFFECTS OF THE INVENTION As described above, according to the present invention, compared to the conventional fence, it is possible to reduce the width on the connecting surface side of the opposing surfaces so that both corners travel on the moving passage side of the loading / unloading device. In addition, it is possible to guide the loading and unloading devices such as forklifts by tilting the facing surfaces of the fences to the loading and unloading area, so that the moving path of the loading and unloading devices is wide and the workability of the loading and unloading device is improved. be able to.
